CROSS REFERENCE TO RELATED APPLICATIONS

The present invention claims priority under Section 119 to theprovisional application filed on Nov. 22, 2010, assigned application No.61/416,273 and entitled Composting Toilet.

FIELD OF THE INVENTION

The present invention pertains to composting toilets that utilizenatural breakdown process of human feces, and more particularly pertainsto composting toilets that are portable and do not require significantenergy utilization.

BACKGROUND OF THE INVENTION

With recent advancements in wireless telecommunications, an increasingnumber of people are able to work in more isolated locations such asboats, vehicles, remote sites and cabins where traditional plumbingsystems and electric power supply may not be available. There istherefore a need for a toilet that provides a convenient, clean, and anenvironmentally safe process for containing and disposing of human wastefor use by people in such remote locations. There is also a need forsuch a toilet that is portable to allow for easy transport of the toiletto the desired remote location.

Traditional portable toilets that have been used in remote locationsutilize chemicals to mask the unpleasant smell of human waste. In suchchemical toilets, both the feces and urine of the user drop down into areceptacle that contains sufficient chemicals, typically liquid, tocover the feces and urine. The chemicals prevent breakdown of the humanwaste and are scented to mask the odor of the waste. However, thechemicals used in such chemical toilets are often environmentallyharmful. Also, chemical toilets are limited in their ability to containmore than a few days worth of human waste, since the receptaclecontaining the chemicals and the human waste may begin to overflow. Andeven if the receptacle is emptied, it requires that additional chemicalsbe on hand to replace the discarded chemicals, otherwise the toilet willnot operate satisfactorily and the smell of additional human waste willnot be masked.

Other toilets have been employed that attempt to utilize composting offeces rather than chemicals. It has long been known that feces may becomposted, that is, the organic matter of human feces decays and becomesa relatively odorless substance that is environmentally friendly, and isin fact well suited for use as a fertilizer. It is also known, however,that the presence of excess urine significantly slows the rate ofcomposting of feces.

Certain prior art composting toilets have a receptacle into which bothfeces and urine fall. These toilets require the user to drop peat mossinto the composting chamber after each use in order to absorb excessurine, since otherwise the excess urine reduces the rate of compostingof the feces. While such toilets utilizing peat moss have been found tobe effective, they require that a supply of peat moss be maintained onhand, and the requirement of adding additional peat moss after each usemakes the composting chamber fill up quickly, requiring an unacceptablyfrequent rate of emptying of the composting chamber. There is a need fora composting toilet that can operate effectively without requiring thecontinual addition of more peat moss.

Other prior art composting toilets have a receptacle into which bothfeces and urine fall, and these composting toilets overcome the problemof excess urine by utilizing heating elements to heat up the feces andurine. A fan circulates air in the composting chamber, to evaporate theexcess urine in order to facilitate improved composting of the feces.However, such heating elements utilize considerable amounts of energy,and the combination of the heating elements and the fan requires toomuch energy for many applications. Thus there is a need for a compostingtoilet that does not require such significant amounts of energy.

Other prior art marine toilets are designed to handle raw sewage in itsconventional liquid form, i.e., urine, fecal matter and flush water, andrequire vacuum pumping of the waste.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

Before describing in detail the particular apparatuses and methodsrelated to a compositing toilet in accordance with the variousembodiments of the present invention, it should be observed that theseembodiments reside primarily in a novel combination of hardware elementsrelated to the claimed apparatuses and methods. Accordingly, thehardware elements have been represented by conventional elements in thedrawings, showing only those specific details that are pertinent to thepresented embodiments so as not to obscure the disclosure with detailsthat will be readily apparent to those skilled in the art having thebenefit of the description herein.

The following embodiments are not intended to define limits as to thestructures or methods of the invention but only to provide exemplaryconstructions. The embodiments are permissive rather than mandatory andillustrative rather than exhaustive.

Generally, the present invention is different from the prior art toiletsin that it can accommodate dry and moist fecal material mixed withdesiccant/peat, which is then hydrated and evacuated from the toilet viaa vacuum process.

In accordance with one embodiment of the present invention there isprovided a toilet comprising a main receptacle for receiving feces andurine of a user. The main receptacle has one or more urine apertures ina lower portion thereof through which urine may flow out of the mainreceptacle, under the influence of gravity, into a urine receptacle. Themain receptacle also has one or more fecal apertures in a lower portionthereof through which feces may leave the main receptacle under theinfluence of gravity. The fecal aperture(s) has a raised perimeter toprevent urine from draining into a fecal receptacle. The fecalreceptacle has at least a portion thereof disposed beneath the fecalaperture for receiving and storing feces that fall downward through thefecal aperture. Said fecal receptacle has at least two apertures forallowing flushing and draining of its contents.

The urine receptacle has at least a portion thereof disposed at a heightlower than the main receptacle for receiving and storing urine. Also,the toilet has at least one urine flow passageway for directing urinethat flows out of the main receptacle into the urine receptacle underthe influence of gravity. The urine flow passageway has raised edges fordirecting urine away from the fecal receptacle.

A composting toilet embodying various features of the present inventionis illustrated in FIGS. 1-9 and referred to generally by referencenumber 100. The toilet 100 has a main receptacle 1 onto which a suitabletoilet seat (not shown) may be mounted. While it is readily appreciatedthat the main receptacle 1 may be a single integral piece or anotherconfiguration, in the preferred and illustrated embodiment the mainreceptacle 1 comprises an upper bowl portion 1 a and a lower bowlportion 1 b. As best seen in FIG. 1, the upper bowl portion 1 a issupported upon and nests inside of the lower bowl portion 1 b. The upperbowl portion 1 a has a fecal aperture 10 a, and the lower bowl portion 1b has a fecal aperture 10 b, with the two fecal apertures 10 a and 10 bbeing in registration with, or substantially aligned with, one anotherwhen the upper bowl portion 1 a is nested inside of the lower bowlportion 1 b. It is not required that the two fecal apertures 10 a and 10b be the same size.

The nested upper and lower bowl portions 1 a and 1 b are supported onand disposed above a fecal receptacle 2. The fecal receptacle 2 has anopening 14 in its upper end that is also below the two fecal apertures10 a and 10 b of the upper and lower bowl portions 1 a and 1 b when themain receptacle 1 is mounted on the fecal receptacle 2. As can be seen,the opening 14 is larger than the openings 10 a and 10 b. This alignmentor registration of the respective apertures and openings allows fecesfrom the user to fall through the two fecal apertures 10 a and 10 b andthrough the opening 14 into an interior of the fecal receptacle 2.

The upper bowl portion 1 a of the main receptacle 1 has an inclinedsurface or surfaces for directing urine of the user, which is impartedinto the main receptacle 1, toward a urine aperture 9 disposed at thefront, lower end of the upper bowl portion 1 a. (The reference numeral 8in FIG. 1 refers to a second urine aperture that is aligned with theurine aperture 9, but is disposed in the section of the upper bowlreceptacle 1 a that has been removed and is not illustrated in FIG. 9.FIG. 5 illustrates both urine apertures 8 and 9.) A raised barrier 10 cencircles the perimeter of the fecal aperture 10 a. This raised barrier10 c prevents the urine from draining into the fecal aperture 10 a. Inan alternative embodiment, the apertures 8 and 9 may be replaced byadditional apertures.

The lower bowl portion 1 b also has an inclined surface or surfaces 11to direct the urine toward the lower bowl urine aperture 12 and hasraised barrier 10 d around the perimeter of aperture 10 b for directingurine during periods of angled use. After striking the surface 11, theurine passes through a slot 30 in a surface 32.

The urine aperture 12 may be located at or near the front, lower end ofthe lower bowl portion 1 b.

Accordingly, urine which is imparted into the upper bowl portion 1 a ofthe main receptacle 1, and which does not pass into the feces aperture10 a of the upper bowl portion 1 a, is diverted under the influence ofgravity toward the urine apertures 8 and 9, and flows down through theurine apertures 8 and 9 under the influence of gravity. After passingdown through the urine apertures 8 and 9, the urine falls onto aninclined surface 11 of the lower bowl portion 1 b, which diverts theurine under the influence of gravity through the slot 30 and towards thelower bowl urine aperture 12. From there the urine flows down throughthe lower bowl urine aperture 12, and flows out of the main receptacle 1under the influence of gravity.

A urine receptacle 3 is connected either directly or indirectly to thelower bowl urine aperture 12, whereby urine flowing out of the mainreceptacle 1 through the lower bowl urine aperture 12 flows into theurine receptacle 3 under the influence of gravity. The contents of theurine receptacle 3, which consists primarily of urine, are thusphysically separate from the contents of the fecal receptacle 2, whichconsists primarily of feces.

This diversion of the urine under the influence of gravity to a separatereceptacle from the fecal receptacle allows for a significantly improvedrate of composting of the feces in the fecal receptacle without the needfor heating elements to evaporate urine from the fecal receptacle or theneed to repeatedly add peat moss into the fecal receptacle to absorbexcess urine.

While the inclined surfaces of the upper and lower bowl portions 1 a and1 b are both directed toward the front of the main receptacle 1 in thepreferred and illustrated embodiment, it is appreciated that thesurfaces of the upper and lower bowl portions 1 a and 1 b do not have tobe directed in a common direction, and they may be directed to anydirection and not necessarily the front direction. A wide variety ofother suitable configurations of urine aperture locations and surfacecontours are also well suited for use with the present invention. Forinstance, the lower surface of the upper bowl portion 1 a may beinclined to direct urine to the left side of the upper bowl portion 1 a,and the urine aperture 9 may be located to the left side of the upperbowl portion 1 a. The inclined surface 11 of the lower bowl portion 1 bangled to direct the urine to any of the right side, front side, leftside, rear side, or any location between the stated directions. Thelower bowl urine aperture 12 may be located to whichever side theincluded surface 11 directs the urine, without regard to the directionwhich the upper bowl portion 1 a directs the urine, or the location ofthe urine aperture 9 of the upper bowl portion 1 a. Also, the aperturesmay be located on opposite sides of upper bowl portion 1 a with theinclined surfaces directing the urine to either or both sides. Aspreviously mentioned the main receptacle 1 may in another embodiment becomprised of a single integral piece without nested upper and lower bowlportions 1 a and 1 b whereby all urine not directed into fecal aperture10 a flows toward the urine aperture 9. This configuration provides fora shorter overall height of toilet 100 for use in low ceilingapplications.

Although the present invention will function without it, the preferredembodiment also has a diverter panel 1 c that is moveable between aclosed position (as illustrated in FIGS. 1 and 3) in which the diverterpanel 1 c extends over and covers the fecal aperture 10 a tosubstantially block urine and feces from passing through the fecalaperture, and an open position (as illustrated in FIG. 4) in which thediverter panel 1 c is moved away from the fecal aperture 10 a so thatthe diverter panel 1 c does not block urine or feces from passingthrough the feces aperture 10 a. In its closed position the upper faceof the diverter panel 1 c is inclined upwardly in a direction toward therear of the lower bowl portion 1 b. See FIG. 4.

In the illustrated embodiment of FIG. 6, the diverter panel 1 c ismounted on a rod 19 that is actuated by turning a lever 20 mounted onthe side surface of upper bowl portion 1 a. The diverter panel 1 c canbe swung back and up by turning lever 20 preventing diverter panel 1 cfrom blocking apertures 10 a and 10 b.

During uses in which the user only urinates, the diverter panel 1 c ismoved in the direction indicated by an arrowhead AA in FIG. 3 to itsclosed position prior to use, preventing the urine from passing throughthe feces aperture 10 a. Following the path of an arrowhead AB, urineimparted toward the feces aperture 10 a impinges on the diverter panel 1c, which covers the feces aperture 10 a and flows off the diverter panel1 c, onto the inclined surface 11 through aperture 12.

Alternatively, the urine may follow a path indicated by an arrowhead AC.Any urine imparted around the circumference of fecal aperture 10 aimpinges on upper bowl portion 1 a and flows around raised barrier 10 cthrough aperture 9. Hence, with the diverter panel 1 c in its closedposition substantially all of the urine is directed into the urinereceptacle 3, and little or no urine flows through the fecal aperture 10a, regardless of the direction or location of urination within the upperbowl portion 1 a of the main receptacle 1. These features facilitateeasy use by both males and females.

In mobile installations where toilet 100 may not be level, the raisedbarrier 10 c prevents urine from entering the fecal aperture 10 a anddripping off the sides of diverter panel 1 c into feces receptacle 2. Analternative design of the raised barrier 10 c is illustrated (see FIG.7) where the raised barrier 10 c merges with the wall of the upper bowlportion 1 a.

During uses in which the user defecates, the diverter plate 1 c is movedto its open position (see FIG. 4) during defecation to allow the fecesof the user to fall straight through the upper bowl feces aperture 10 aand the lower bowl portion feces aperture 10 b, through the opening 14of the feces receptacle 2, and into the feces receptacle 2 for storageand composting of the feces within the fecal receptacle 2. See FIG. 4where arrowhead AD indicates the direction of the feces and arrow AEindicates the direction of movement of the diverter plate 1 c to theopen position.

Alternatively, for defecation, the diverter panel 1 c may be moved toits closed position, and a piece of suitable biodegradable paper or thelike, such as filter paper, may be placed over the feces aperture 10 a.With the biodegradable paper restricted from falling through the fecesaperture 10 a by the diverter panel 1 c, the feces of the user dropsdown onto the biodegradable paper. Subsequent movement of the diverterpanel 1 c to its open position allows the feces and biodegradable paperto drop down together through the upper bowl feces aperture 10 a andlower bowl portion feces aperture 10 b, through the opening 14 of thefeces receptacle 2 and into the feces receptacle 2.

During those intervals of use in which the user is urinating rather thandefecating, the diverter panel 1 c is moved back to its closed position,to prevent substantially all urine imparted during urination frompassing into the feces receptacle 2. Accordingly, by moving the diverterpanel 1 c between it open and closed positions at the appropriate time,substantially all urine will be directed or diverted into the urinereceptacle 3, to keep the feces receptacle 2 substantially free ofurine. In this regard, in one alternative embodiment, the diverter panelmay be biased to its closed position, such as by a spring or the like,so that it may be held in its open position during defecation and maysimply be released during all other times.

Any of several different agitator configurations are well suited foragitating the fecal contents of the feces receptacle 2, such as theagitator 15 shown in FIG. 2, which comprises a rod having a helicalshape with an axis extending generally diagonally from a vertical axis.The agitator 15 is disposed for rotation within the feces receptacle 2,with the opposite ends of the central axle of the agitator 15 rotatablyengaged with the feces receptacle 2, and one end of the agitator 15being engaged with a handle 16 to allow manual rotation of the agitator15.

While it is not necessary, it has been found that adding a small amountof peat moss or the like to the bottom of the feces receptacle 2 priorto the first use of the toilet and prior to the first subsequent useafter the feces receptacle has been emptied, provides good results. Theagitator 15 should be long enough to reach the peat moss, but it is notnecessary that it extend down to the bottom surface of the fecesreceptacle 2. In fact, in some embodiments, it is preferred that a spacebe provided between the lowermost extension of the agitator and thebottom surface of the feces receptacle 2 so that composted materialadjacent the bottom of the feces aperture is not re-mixed with freshfeces; the agitator only agitating the fresh feces.

For removing the contents of the feces receptacle 2, an aperture 17 (SeeFIG. 6) is designed to connect to a hose or suction device. For thisembodiment the aperture 17 is preferably located near the bottom surfaceof the feces receptacle 2 but alternative locations such as the bottomor the top with a hose reaching to the bottom of feces receptacle 2 arealso acceptable. The aperture 17 allows for removing the contents of thefeces receptacle 2 by vacuum or another suitable device such as a pump.Generally the contents of the tank are in a non-free flowing state,which would normally prevent vacuum removal.

For this purpose a second aperture 18 (see FIG. 6) is provided to allowhydration of the contents using (for instance) a standard garden hose.The preferred embodiment utilizes a spherical bearing for the purpose ofdirecting the stream of water however it would also be suitable to filltank via other methods.

In another embodiment the fecal material may be transferred from fecalreceptacle 2 to a remote receptacle via any suitable means of transferwhether it be by conveyor, air pressure, suction, or water. FIG. 8illustrates an auger conveyor.

It may be necessary for the decomposition process to have sufficientairflow throughout fecal receptacle 2 to allow aerobic bacteria tothrive. Although it is not necessary to have a fan creating thisairflow, the use of said fan will optimize the decomposition and reducethe odors in the living space. FIG. 9 illustrates one embodiment whichcould be used transient situations such as camping. To maximizeportability, a fan hose 21 is housed inside a slot molded into the fecalreceptacle 2 during times of travel and non use. During times of toiletuse, the hose 21 is removed from said slot and extended outside theliving space. A fan housing 22 is mounted at the end of the hose runmaximizing negative airflow.
